GRAPPLING TOOL FOR JOISTS AND STUDS Filed July 29, 1947 w I a PatentedJune 7, 1949 UNITED STATES PATENT OFFICE 2,472,500 GRAPPLING TOOL FORJOISTS AND STUDS Laverne E. Swanson, Manistee, Mich. Application July29, 1947, Serial No. 764,475

1 Claim.

This invention relates to new and useful improvements in grappling toolsfor joists and studs.

The primary object of my invention is to provide a tool of the characterspecified primarily designed for use by carpenters in rough constructionwork, in grappling joists and studs and drawing into place sheathing andother building materials.

Formerly, carpenters have used chisels and other instruments as prys indoing this work, but such means is very unsatisfactory and timeconsuming and far inferior to my novel grappling tool in handlingconstruction material.

A further object of my invention is to provide a tool of this kind thatis simple and economical in construction and highly eflicient anddurable in use.

With the foregoing and other objects in view that will appear as thenature of my invention is better understood, the same consists in thenovel features of construction, combination and arrangement of partsillustrated in the accompanying drawing and more particularly pointedout in the appended claims.

In the accompanying drawing, which is for illustrative purposes only andis therefore not drawn to scale:

Figure 1 is a side elevation of a grappling tool, constructed inaccordance with my invention.

Figure 2 is a vertical transverse section, taken on line 2-2 of Figure1.

Figure 3 is a horizontal section, taken on line 3-3 of Figure 1, andFigure 4 is a plan view.

Referring to the drawings for a more particular description of myinvention, and in which drawings like parts are designated by likereference characters throughout the several views, my grappling tool,generally indicated by the reference letter A, is preferably constructedfrom a single continuous bar or strip of metal of rectangular form incross section, and comprises the straight elongated handle I, bent atone end to form a U-shaped grapple 2.

In carrying out my invention, the transverse base portion 3 of theU-shaped grapple 2, is formed with a central elongated longitudinal ribl of V-shape form in cross section, while the shorter side 5 of thegrapple 2 is formed with a pair of corresponding laterally spacedlongitudinally disposed ribs 6 and I. The ribs 5 and I are arranged inalternating relation with the rib 4, and the ribs 4, 6 and 1 beveled toa knife edge to provide a better grip on the joist, stud or othermaterial.

From the foregoing description taken in connection with the drawings, itis thought that the construction, operation and advantages of myinvention will be readily understood, without requiring a more extendedexplanation.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is:

A grappling tool for joists or studs, constructed from a singlecontinuous bar or strip of metal of rectangular form in cross section,and comprising a straight elongated handle formed at one end with aU-shaped grapple hook, a central V-shaped longitudinal rib tapered to aknife edge, formed on the inner edge of the transverse base portion ofthe grapple hook, and a pair of corresponding laterally spacedlongitudinally disposed V-shaped ribs tapered to a knife edge, on theinner edge of the shorter arm of the U- shaped grapple hook, with thefirst and last mentioned ribs disposed in alternating relation.
